The MIC2583-LYQS from Microchip Technology is a Single-Channel Positive Voltage Hot-Swap Controller eFuse IC that has been designed to allow the safe insertion of boards into live system backplanes. It requires an input voltage of 2.3 - 13.2 V. This eFuse IC offers programmable in-rush current limiting and current regulation to limit the in-rush current regardless of load capacitance. It also provides output voltage slew rate control in harsh, critical power supply environments. This eFuse IC offers a circuit breaker functionality to latch the output MOSFET off if the current-limit threshold is exceeded for a determined period and has a fast response to short-circuit conditions. It includes an auto-restart function upon detecting an over-current condition.
This eFuse IC includes an optional dual-level over-current threshold to detect excessive load faults, programmable output under-voltage detection, under-voltage lockout (UVLO) protection, auto-restart function, power-on-reset status output, power good (PG) status output, and fault status output functionalities to prevent over-load-related damages. It is available in a surface-mount package that measures 4.9 x 3.9 x 1.62 mm and is ideal for RAID systems, base stations, PC board hot-swap insertion and removal, +12V backplanes, and network switch applications.
